I almost get thrown out at C4L event for filming a uninvited crasher!

I filmed an uninvited crasher being thrown out by Campaign for Liberty security. Instead of worrying about the crasher, the secuirty then comes after me and demands that I shut off my camera. They then come over and grab my camera and point it away to keep me filming what is going on. Am I overreacting to being censored? Watch this footage and you decide.
